The Colorado Department of Agriculture’s State Veterinarian’s Office has released all quarantine and hold orders associated with a horse that recently tested positive for equine herpesvirus (EHV-1).

The affected horse, a 6-year-old gelding from Texas, is part a Quarter Horse team used during the 2013 National Western Stock Show rodeo to pull a stagecoach during rodeo performances.

The horse began showing clinical signs January 27 and was transported to the Colorado State University Veterinary Teaching Hospital for diagnosis and treatment. The diagnosis of equine herpesvirus was confirmed January 28. The other horses from the team tested negative for EHV-1; subsequently, all quarantine and hold orders have been released. 

The gelding was transported with special documentation and was received directly back to his ranch of origin through collaboration with Texas Animal Health Commission (TAHC) officials. The TAHC will complete the observation and movement restrictions related to the affected gelding
